Abstract
The supporting legs of TianTuo-3 microsatellite support the satellite and can protect the antennas and other devices, but original design relies on experience of engineers and experiment. The design period is long and the cost is expensive, and structure is always conservative. Optimization Driven Design Process (ODDP) is applied and a multi-step optimization strategy which is more efficient is proposed to find a better design of the supporting legs in TianTuo-3 Microsatellite. First, an optimal topology configuration of leg is obtained by utilizing Solid Isotropic Material Penalty (SIMP) approach, considering minimization of compliance. Then, a multi-objective shape and size optimization is built considering strength, stiffness and stability requirements based on Non-dominated Sorting Genetic Algorithm-II (NSGA-II). Finally, after several rounds of design iteration by engineer, a brand new design is given. The mass of one leg, axial fundamental frequency and maximum von Mises stress are decreased by 17.93%, 4.52% and 11.67% respectively compared with original design. Buckling factor and lateral fundamental frequency are increased by 74.24% and 6.52% respectively. It shows that the multi-step strategy has advantages than traditional design process.
